您的要求无法解决为一组可安装的软件包（Composer更新）

Question

尝试安装此软件包时出现此问题

"codesleeve/laravel-stapler": "1.0.*"

这是我的composer.json文件

"require": {
    "php": ">=5.5.9",
    "laravel/framework": "5.2.*",
    "laravel/socialite": "^2.0",
    "laravelcollective/html": "5.2.*",
    "greggilbert/recaptcha": "^2.1",        
    "bican/roles": "2.1.*",
    "kodeine/laravel-acl": "~1.0@dev",
    "nesbot/carbon": "^1.21",
    "dansmith/laravel5-foundation": "0.3.*",
    "codesleeve/laravel-stapler": "1.0.*"
},

这是错误：
